The first post has been updated with version 0.9.5.
The changelog isn't very big but it was a lot of work and a lot of testing to get Visual Studio 2022, Visual Studio Code and VSCodium to work with DwmExtendFrameIntoClientArea and Blur Behind. Visual Studio 2022 was actually quite easy. But dealing with Electron for VSCode was not fun. I updated the documentation file (DwmColorBlurMica.txt) with some details on how to get it working well with those apps and also Windows Terminal.
As a reminder, Visual Studio 2022, Visual Studio Code, VSCodium and Windows Terminal can enjoy DwmExtendFrameIntoClientArea and Blur Behind with the default Windows Dark (aero) theme. They do have their own special instructions, but they do not require installing a third-party msstyles at least.
